I45.4

Billable

Nonspecific intraventricular block

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A heart rhythm problem where electrical signals are delayed or blocked as they travel through the lower chambers of the heart, but the specific cause cannot be clearly identified.

Coding Tips

  • •Use this code when conduction delay is documented in the ventricles without a more specific diagnosis
  • •Differentiate from bundle branch blocks which have more specific codes (I44.x)
